Depending on the type of food and the conveying structure, the weighing and measuring methods used are also different. For liquid foods, they are mostly measured by flow meters, while for solid foods, they are mostly measured by electronic scales.

[0003] The existing patent application with publication number CN108974460A discloses an automatic metering, boxing and basket loading production line for cooked crayfish, including main line A and auxiliary line B. A raw material guide groove is arranged between main line A and auxiliary line B, and the raw material guide groove is rotatable freely between main line A and auxiliary line B; the main line A includes a first lifting mechanism, an automatic box dividing mechanism, a picking conveyor, a first picking operation table, a second lifting mechanism, a combination scale, a combination scale platform, a material distributing mechanism, a double-layer packaging tray conveyor, a second picking operation table, and a surplus material recovery table; the auxiliary line B includes a flow-limiting feeder, a box feeding conveyor mechanism, a belt weigher, and a non-powered roller conveyor mechanism.

[0004] In the above technical solution, a linear conveyor is used for the conveying of food, and a weighing belt conveyor is used for weighing, but the weighing belt conveyor is used for weighing after packaging; before packaging, a combination scale is used for weighing.

[0055] S5. Feed crayfish between the two scrapers and weigh and measure them through the weighing mechanism;

[0056] S6. Drive the scraper to move along the annular material channel through the transmission mechanism, thereby driving the crayfish to displace;

[0057] S7. During the transfer process of the crayfish, the functional components perform adaptive processing on the crayfish.

[0058] The crayfish metering and conveying mechanism, frying production line and application method of the present invention have the following beneficial effects compared with the prior art:

[0059] (1) By setting up an annular material channel and a weighing mechanism, when the scraper conveys crayfish driven by the transmission mechanism, not only can live or fried crayfish be weighed, but also the volume of this equipment is reduced; in addition, the transmission mechanism is installed in the power cavity inside the annular material channel, and the top cover also penetrates the power cavity. The part of the top cover that penetrates the power cavity is used to install support components such as electrical cabinets and pumps, thus making full use of the space of the annular conveying mechanism. On the basis of the original small floor area, the space occupation is further reduced; and the part of the top cover that penetrates the power cavity is a through structure, so that the support components can be maintained from two directions, ensuring the convenience of maintenance and also facilitating electrical connection;

[0060] (2) In this metering and conveying mechanism, the transmission mechanism is a sprocket transmission mechanism, and the top cover is supported by the transmission shaft of the transmission mechanism without other fixing components. In this way, not only the covering of the power cavity is realized, but also the assembly structure of the top cover is simplified, and the top cover is easy to disassemble for maintenance work;

[0061] (3) In the top cover, the power cavity is covered by a cover plate, the inner cylinder penetrates the power cavity, and there are pillars around the inner cylinder for structural strengthening. At the same time, this penetrating structure also realizes the radial limit of the cover plate relative to the transmission shaft, so as to ensure the stability of the installation structure and improve the overall structural strength; at the same time, there is a partition at the lower end of the pillar, which is convenient for carrying support components, increasing the volume of the support components and ensuring the convenience of maintenance;

[0062] (4) By setting a rotating support in the conveying mechanism for installing a three-axis displacement mechanism and a guide rail, it can be used to install functional components for processing crayfish; at the same time, the three-axis displacement mechanism and the guide rail can be easily rotated through the rotating support, so that the three-axis displacement mechanism and the guide rail are separated from the top cover, which not only facilitates the maintenance and cleaning of the conveying mechanism, but also does not interfere with the opening of the top cover; at the same time, in addition to installing functional components, the guide rail also supports the three-axis displacement mechanism to move, ensuring the stability of the adjustment structure;

[0063] (5) When limiting the three-axis displacement mechanism and the guide rail, the guide rail is connected to the top cover by bolts, and the three-axis displacement mechanism is connected to the guide rail by screws, so as to improve the convenience of fixing the three-axis displacement mechanism and the guide rail and ensure the relative position of the three-axis displacement mechanism and the guide rail;

[0064] (6) By setting the second flexible plate with a mesh plate structure and a vibration motor, when dispersing crayfish through the vibration motor, the oil, water or debris attached to the crayfish can be removed, so that the produced crayfish meet the standards. At the same time, it is also convenient for machine vision inspection through the camera. Description of the Drawings

[0077] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0078] As Figures 1 - 10 shown, the crayfish metering and conveying mechanism of the present invention includes a base 1, a scraper 2, a transmission mechanism 3, a top cover 4, a weighing mechanism 5, a rotary support 6, a three-axis displacement mechanism 7, a guide rail 8, a functional component 9, a second flexible plate 10 and a vibration motor 1010;

[0079] The deep-frying production line of the present invention includes the above-mentioned crayfish metering and conveying mechanism, and also includes an input conveying mechanism 100, an output conveying mechanism 200 and a deep fryer 300.

[0080] As Figure 1 、 Figure 8 and Figure 9 shown, the base 1 is provided with an annular material channel 101, and the top of the annular material channel 101 is open; a power chamber 102 is arranged inside the annular material channel 101, and the top of the power chamber 102 is open. Among them, a plurality of scrapers 2 are arranged in the annular material channel 101; the transmission mechanism 3 is arranged in the power chamber 102, and the transmission mechanism 3 is used to drive the scraper 2 to move along the annular material channel 101;

[0081] In the above structure, the annular material channel 101 is used to receive crayfish, and then driven by the transmission mechanism 3, the scraper 2 is driven to move in the annular material channel 101, so as to realize the conveying of crayfish. During this process, since the top of the annular material channel 101 is open, it is convenient to perform processes such as manual screening, automatic screening, cooling, and air drying on crayfish;

[0082] Meanwhile, since the power chamber 102 is located inside the annular material channel 101, this makes the mechanism have the advantage of a compact structure and reduces the floor area.

[0083] As Figures 3 - 6 shown, the top cover 4 shields the top of the power chamber 102. A part of the top cover 4 penetrates through the power chamber 102, and the part of the top cover 4 that penetrates through the power chamber 102 is of a through structure;

[0084] In the above structure, the top cover 4 is used to shield the power chamber 102 to achieve the function of safety protection. At the same time, a part of the top cover 4 also passes through the power chamber 102, and the part passing through the power chamber 102 is set as a through structure. In this part, it can be used to install support components, such as industrial control components for installing screening, air-drying and other processing components; this reduces the occupied area of support components such as electrical cabinets and air pumps in this mechanism, making the structure of this mechanism more compact; at the same time, the through structure also facilitates electrical connection and maintenance work between components;

[0085] The weighing mechanism 5 is arranged in the annular material channel 101 and is used for weighing and measuring crayfish;

[0086] As Figure 4 and Figure 5 shown, specifically, the weighing mechanism 5 includes a first flexible plate 51 and an electronic scale 52. Among them, the first flexible plate 51 is a part of the bottom surface of the base 1 to support the crayfish during transportation; the electronic scale 52 is arranged outside the annular material channel 101, and the electronic scale 52 is connected to the base 1 and corresponds to the first flexible plate 51;

[0087] In the above structure, the first flexible plate 51 serves as a part of the bottom surface of the base 1. In this way, when the scraper 2 drives the crayfish to move, the crayfish will be transferred to the first flexible plate 51. At this time, the weight is transmitted to the electronic scale 52, and the weighing and measuring can be carried out through the electronic scale 52.

[0088] The design of this metering and conveying structure can weigh and measure both live crayfish and fried crayfish, and is not restricted by the state of the crayfish.

[0089] As Figure 3 and Figure 9As shown in the figure, the base 1 includes a first bottom plate 11, an inner ring plate 12, an outer ring plate 13, and a support plate 14. Among them, the first bottom plate 11 is in an annular plate-like structure. The inner ring plate 12 and the outer ring plate 13 are oppositely arranged on the inner and outer sides of the first bottom plate 11 to form an annular material channel 101. The inner side of the inner ring plate 12 is a power chamber 102. Two support plates 14 are oppositely arranged in the power chamber 102 to support the transmission mechanism 3. There is a through hole 103 between the two support plates 14, and a part of the top cover 4 penetrates through the through hole 103.

[0090] In the above structure, the base 1 constitutes the annular material channel 101 and the power chamber 102 through the first bottom plate 11, the inner ring plate 12, and the outer ring plate 13, and forms the through hole 103 by arranging the support plate 14 in the power chamber 102.

[0091] During specific assembly, the transmission mechanism 3 is installed on the support plate 14 to drive the scraper 2 to move.

[0092] Furthermore, the top cover 4 passes through the power chamber 102 and the through hole 103, so that the positioning of the top cover 4 relative to the base 1 can be realized, ensuring the convenience of assembly and the structural stability after assembly.

[0093] As Figure 8 and Figure 9 shown in the figure, the transmission mechanism 3 includes a transmission shaft 31, a motor 32, a sprocket 33, a chain 34, a support seat 35, and a plain bearing 36. Among them, one transmission shaft 31 is arranged on each of the two support plates 14, and the transmission shaft 31 is a stepped shaft. The motor 32 is arranged outside the support plate 14, and the main shaft of the motor 32 is connected to the small-diameter end of the transmission shaft 31. One sprocket 33 is arranged on each of the two transmission shafts 31, and the two sprockets 33 are engaged with the chain 34. The top cover 4 is supported by the transmission shaft 31, so that there is a gap 401 between the top cover 4 and the inner ring plate 12, and the scraper 2 passes through the gap 401 to connect the transmission mechanism 3.

[0094] In the above structure, when the transmission mechanism 3 operates, the motor 32 drives one of the transmission shafts 31 and the sprocket 33 to rotate, and then relies on the chain 34 to drive the other transmission shaft 31 and the sprocket 33 to rotate. With the movement of the chain 34, the scraper 2 will move in the annular material channel 101 to realize the transportation of crayfish.

[0095] Specifically, in this structure, the transmission shaft 31 supports the top cover 4. During assembly, bearing supports can be set on the top cover 4 and the support plate 14, and the end of the transmission shaft 31 is inserted into the bearing support, which not only ensures the support of the transmission shaft 31 for the top cover 4 and the assembly stability of the transmission shaft 31, but also does not interfere with the rotation of the transmission shaft 31.

[0096] When the top cover 4 is fastened to the power chamber 102, a gap 401 is left between it and the inner ring plate 12 of the base 1 to provide an assembly space for connecting the chain 34 of the transmission mechanism 3 to the scraper 2.

[0097] As Figure 8 shown, the support seat 35 is arranged on the support plate 14 and surrounds the transmission shaft 31; the plain bearing 36 is sleeved on the transmission shaft 31, one side of the plain bearing 36 abuts against the stepped surface of the transmission shaft 31, and the other side abuts against the support seat 35;

[0098] Specifically, the shaft hole of the plain bearing 36 does not contact the transmission shaft 31 to reduce friction;

[0099] In the above structure, after the top cover 4 is installed, since the top cover 4 also needs to be provided with a support assembly, it has a relatively large weight. At this time, in order to ensure the assembly stability of the transmission shaft 31, the transmission shaft 31 is set as a stepped shaft structure. At the same time, the support seat 35 is installed on the support plate 14, and the support seat 35 abuts against the stepped surface of the transmission shaft 31 through the plain bearing 36, so as to share the force transmitted from the transmission shaft 31 to the support plate 14. In this way, the support plate 14 has a larger force-bearing area, thus ensuring the structural stability;

[0100] Specifically, in this structure, the top cover 4 realizes axial positioning relative to the transmission shaft 31 by its own weight, and realizes radial positioning relative to the transmission shaft 31 by the part passing through the power chamber 102; thus, the assembly structure of the top cover 4 is simplified, and the top cover 4 is also easy to disassemble for maintenance work;

[0101] As shown in 8 and Figure 9 shown, the top cover 4 includes a cover plate 41, an inner cylinder 42, a support column 43 and a second bottom plate 44. Among them, the cover plate 41 abuts against the transmission shaft 31, and the side edge of the cover plate 41 extends towards the inner ring plate 12 to form a gap 401 with the inner ring plate 12;

[0102] In the above structure, the side edge of the cover plate 41 extends towards the inner ring plate 12 to form a gap 401 for connecting the transmission mechanism 3 and the scraper 2; in this way, the closure of the power chamber 102 can be ensured as much as possible to reduce the possibility of foreign objects entering;

[0103] The inner cylinder 42 is arranged in the middle of the cover plate 41, and the inner cylinder 42 penetrates through the through hole 103; the support column 43 is arranged on the side of the inner cylinder 42, the support column 43 penetrates through the through hole 103, and the support column 43 abuts against the side edge of the support plate 14;

[0104] In such a structure, the parts of the top cover 4 passing through the power chamber 102 are the inner cylinder 42 and the support column 43, and at the same time, they also penetrate through the through hole 103. In this way, the middle part of the base 1 is a structure that is vertically through, so as to facilitate the assembly of the support assembly and maintenance work;

[0105] In this structure, in order to ensure the stability of the inner cylinder 42, struts 43 are provided on its side for structural reinforcement, and the struts 43 abut against the side edge of the support plate 14, so as to ensure the structural stability of the top cover 4 relative to the base 1 and facilitate positioning during assembly;

[0106] The second bottom plate 44 is arranged at one end of the strut 43 passing through the through hole 103, and there is a gap between the second bottom plate 44 and the inner cylinder 42 to form an open structure;

[0107] Furthermore, a second bottom plate 44 is also arranged at the bottom end of the strut 43, so that the above-mentioned support components can also be installed through the second bottom plate 44, and there is a gap between the second bottom plate 44 and the inner cylinder 42, so that the support components can be exposed, facilitating maintenance.

[0108] In some embodiments, support legs are arranged on the bottom surface of the base 1 and the bottom surface of the second bottom plate 44, and both are in direct contact with the bottom surface to achieve stable support, which can reduce the load on the transmission shaft 31; thus, one end of the transmission shaft 31 is positioned by the fixed structure base 1, and the other end is positioned by the detachable top cover 4.

[0109] Furthermore, the vacant position on the top surface of the top cover 4 can also be used to install support components.

[0110] Such as Figure 1 and Figure 2 As shown, a plurality of rotary supports 6 are arranged on the base 1; a plurality of three-axis displacement mechanisms 7 and guide rails 8 are both arranged, one end of each of the three-axis displacement mechanisms 7 and the guide rails 8 is rotatably connected to the rotary support 6, and one end of each of them is lapped on the top cover 4; the guide rail 8 has an arc-shaped plate structure for supporting the rotation of the three-axis displacement mechanism 7; the functional components 9 are arranged on both the three-axis displacement mechanism 7 and the guide rail 8, and the functional component 9 is one or several of a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component;

[0111] In the above structure, the three-axis displacement mechanism 7 and the guide rail 8 are used for installing the functional component 9, and at the same time, the guide rail 8 is also used for the self-position adjustment of the three-axis displacement mechanism 7;

[0112] Specifically in application, the action end of the three-axis displacement mechanism 7 and the side surface of the guide rail 8 are used to install the functional component 9. On the movable end of the three-axis displacement mechanism 7, the functional component 9 that needs displacement adjustment is installed, while on the side surface of the guide rail 8, the functional component 9 that does not need displacement adjustment is installed;

[0113] Since one end of each of the three-axis displacement mechanism 7 and the guide rail 8 is connected to the base 1 through the rotary support 6, the three-axis displacement mechanism 7 and the guide rail 8 can rotate to selectively lap on the top cover 4, thus striding across the annular material path 101, and then performing related process operations through the functional component 9;

[0114] Specifically, the guide rail 8 is set in an arc-shaped structure and can be rotated to the running track at one end of the top cover 4 where the three-axis displacement mechanism 7 is lapped. In this way, when making adjustments, the three-axis displacement mechanism 7 can be adjusted first, so that the end of the three-axis displacement mechanism 7 slides on the guide rail 8 to disengage from the top cover 4 until it is completely placed on the base 1. Then, the guide rail 8 is rotated to disengage the guide rail 8 from the top cover 4; this structure can prevent the three-axis displacement mechanism 7 from being suspended and stressed, thereby avoiding damage to the rotating support 6 and the three-axis displacement mechanism 7, and can also ensure the accuracy of the three-axis displacement mechanism 7;

[0115] Among them, the three-axis displacement mechanism 7 can be provided with moving wheels on the end face and move in cooperation with the guide rail 8 with the moving wheels; or sliders can be provided on the end face of the three-axis displacement mechanism 7 to cooperate with the guide rail 8;

[0116] In this structure, the guide rail 8 is used for both the moving support of the three-axis displacement mechanism 7 and the installation of the functional component 9, thus achieving full utilization.

[0117] The setting of this adjustable structure can prevent the three-axis displacement mechanism 7 and the guide rail 8 from interfering with the cleaning of the annular material path 101 and the disassembly and maintenance of the top cover 4, thereby improving the convenience of application; after the relevant cleaning and maintenance work is completed, the three-axis displacement mechanism 7 and the guide rail 8 are rotated to lap the top cover 4 and lock and fix it.

[0118] For the functional components carried by the three-axis displacement mechanism 7 and the guide rail 8, including but not limited to: one or several of a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component. In this way, functions such as photographing and detecting, vacuum suction and screening, air supply and drying, spray cleaning and medium spraying can be realized. Among them, photographing and detecting and vacuum suction and screening can realize the automatic detection and sorting of crayfish, while air supply and drying can realize the drying of crayfish, spray cleaning is used for the cleaning of crayfish, and medium spraying is for the spraying work of treatment liquids such as cleaning agents; thereby making this device applicable to the front and back metering transportation and related treatment work of crayfish frying;

[0119] Specifically, the camera is an industrial camera for photographing and comparative detection;

[0120] Specifically, the vacuum suction pipe is arranged on the three-axis displacement mechanism 7 so that the three-axis displacement mechanism 7 can drive the vacuum suction pipe to displace to achieve position adjustment.

[0121] Such as Figure 2As shown in the figure, the guide rail 8 includes a limiting section 81, a flat plate section 82 and a screw 83. Among them, the cross-section of the limiting section 81 is in a U-shaped structure for end limiting when the three-axis displacement mechanism 7 rotates; there is one flat plate section 82 at each end of the limiting section 81, and one of the flat plate sections 82 is connected to the rotating support 6; the screw 83 is arranged on the limiting section 81 close to the other flat plate section 82, and the flat plate section 82 close to the screw 83 is fixedly locked with the top cover 4 by bolts; the screw 83 is fixedly locked with the end of the three-axis displacement mechanism 7 by a nut.

[0122] In the above structure, the guide rail 8 has a limiting section 81 in the middle and flat plate sections 82 at both ends. The guide rail 8 is in sliding fit with the three-axis displacement mechanism 7 through the limiting section 81 in the middle. Since the guide rail 8 needs to be adjusted after the three-axis displacement mechanism 7 is adjusted in place, if the guide rail 8 only has a limiting section 81 with a U-shaped cross-section, interference will occur between the limiting section 81 and the moving wheels or sliders on the three-axis displacement mechanism 7 when the guide rail 8 rotates.

[0123] After setting the flat plate section 82, the movable end of the three-axis displacement mechanism 7 can be first moved to the flat plate section 82 connected to the rotating support 6. At this time, when the guide rail 8 is rotated, no interference problem will occur, so as to realize the rotation adjustment action of the guide rail 8.

[0124] When fixing the three-axis displacement mechanism 7, the guide rail 8 and the top cover 4, the other flat plate section 82 of the guide rail 8 is fixedly connected to the top cover 4 by bolts. Then, the end of the three-axis displacement mechanism 7 is engaged with the screw 83 on the guide rail 8 and locked by a nut, so as to realize the relative fixation of the three-axis displacement mechanism 7, the guide rail 8 and the top cover 4 to ensure the stability of the structure during application.

[0125] Specifically, a screw can also be set on the top cover 4, and a U-shaped notch can be set on the flat plate section 82. In this way, when the guide rail 8 is rotated, the U-shaped notch can be clamped onto the screw; attention needs to be paid to the opening direction of the U-shaped notch to avoid interfering with the rotation action of the guide rail 8.

[0126] As Figure 4 、 Figure 6 and Figure 7 shown, the second flexible plate 10 is a part of the bottom surface of the base 1 to support the crayfish during transportation, and the second flexible plate 10 is a mesh plate; the vibration motor 1010 is connected to the base 1 and corresponds to the second flexible plate 10.

[0127] In the above structure, when the scraper 2 pushes the crayfish for transportation, it is inevitable that there will be a stacking phenomenon, which will affect the photographing and detection of the crayfish by the camera in the functional component 9. Therefore, it is necessary to disperse the crayfish.

[0128] Specifically, after the crayfish gather on the second flexible plate 10, the corresponding camera is synchronized. At this time, through the vibration of the vibration motor 1010, the crayfish can be dispersed, so that the crayfish are laid flat, facilitating photographing and detection.

[0129] Meanwhile, the water or oil carried by the crayfish will also quickly fall off and seep through the net-like second flexible plate 10. A liquid collection measure can be set on the lower side of the second flexible plate 10 to prevent the water or oil from spreading.

[0130] Here, it is necessary to control the mesh holes of the second flexible plate 10 to be extremely small to avoid lobster jamming.

[0131] As Figure 10 shown, the input conveyor mechanism 100 is arranged on one side of the fryer 300 for inputting crayfish into the fryer 300; the output conveyor mechanism 200 is arranged on the other side of the fryer 300 for outputting crayfish from the fryer 300; the crayfish metering and conveying mechanism is arranged at one end of the input conveyor mechanism 100 away from the fryer 300 and / or at one end of the output conveyor mechanism 200 away from the fryer 300; for the crayfish metering and conveying mechanism on the input side, the functional components 9 are a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component; for the crayfish metering and conveying mechanism on the output side, the functional components 9 are a camera, a vacuum suction pipe, an air knife and a spray component.

[0132] As Figure 10 shown, the input conveyor mechanism 100 is arranged on one side of the fryer 300 for inputting crayfish into the fryer 300; the output conveyor mechanism 200 is arranged on the other side of the fryer 300 for outputting crayfish from the fryer 300; the crayfish metering and conveying mechanism is arranged at one end of the input conveyor mechanism 100 away from the fryer 300 and / or at one end of the output conveyor mechanism 200 away from the fryer 300; for the crayfish metering and conveying mechanism on the input side, the functional components 9 are a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component; for the crayfish metering and conveying mechanism on the output side, the functional components 9 are a camera, a vacuum suction pipe, an air knife and a spray component;

[0133] For the above structure, when performing the frying process of crayfish, a metering and conveying mechanism can be set first to convey and perform related processing on the front end of the crayfish.

[0134] Specifically, it can be equipped with a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component to realize the front-end detection and screening, cleaning and drying of crayfish, and the spraying of treatment liquid.

[0135] After the front-end treatment, the crayfish are sent into the fryer 300 by the input conveyor mechanism 100 for frying, and then lifted and output by the output conveyor mechanism 200 and transferred to the metering and conveying mechanism at the rear end.

[0136] In the metering and conveying mechanism at the rear end, the functional components are a camera, a vacuum suction pipe, an air knife, and a spray assembly for secondary detection and picking, air blowing and cooling, and spraying of the treatment liquid.

[0137] Specifically, the input conveyor mechanism 100 and the output conveyor mechanism 200 can adopt chain plate conveyors, which is conducive to draining water and oil.

[0138] Such as Figure 4 and Figure 6 As shown, a discharge opening 104 can be opened on the first bottom plate 11 of the base 1 to discharge the processed crayfish.

[0139] The application method of the frying production line of the present invention includes the following steps:

[0140] S1. Set a crayfish metering and conveying mechanism at the front end and / or the end of the frying production line;

[0141] S2. Select appropriate functional components 9 and assemble them onto the three-axis displacement mechanism 7 and the guide rail 8;

[0144] S5. Feed crayfish between the two scrapers 2 and weigh and measure them through the weighing mechanism 5;
